Function of the whole machine
v All units are stationary .There is no need to move the printing
unit when changing the printing plate so that the quality of
overprinting can be guaranteed
v Each unit of the machine is independently drive by “Rexroth ” Servo motor which is made in Germany .it has the high precision
since there is no accumulated error of gears’ gap
v The machine uses intelligent control and management .It can set
and store multi parameter .All the function are clear on the
humanized operating interface
v The adjusting system is precise so that we can get a good effect
when adjusting the pressure of linking and printing
v The whole machine adopt an enclosed structure combined with
induced draft fans outside ,which can guarantee the cleanness of
internal machine as well as the precision of cardboard feeding and
printing
v Conveyor belts are used to increase the distance between printing
units while no more induced draft fans is added in order to have
the good printing quality and energy conservation
Feeding Unit
v It is independently driven by servo motor ,having a long service
life since there is no wear and tear of gear box . It also has the
function of long-travel feeding
v The induce draft fans can effective remove the dust of internal
machine and the dust on the surface of cardboard together with
brush to improve the printing quality
v It is convenient to adjust the location of side/ front guides and
the gap between feeding rollers by PLC
The electric control system
v The centralized control of electric system can automatic control
the units of feeding ,printing ,polishing and conveying .
v Each unit of the machine is independently driven by “Rexroth ” servo motor which is made in Germany to carry out the operation of
feeding ,printing and polishing etc of cardboard
v The centralized control of German “Rexroth ” servo motor is combined with IO expansion and sensor inspection of
each unit ,which can control and inspect the distance between the
units and warn
v The operation interface of upper computer can centralized control
and store the parameter of orders in each unit .With function of
human-computer interaction ,the operator can adjust the speed
,production quantity ,the gap and the location by inputting
parameters
v Each unit is equipped with human-computer interface ,with which we
can adjust the parameter of gap and location of this unit
Printing unit
v The printing unit is independently driven by servo motor .It has a
simple mechanical structure which is easy to be maintained and can
reduce the transmission error caused by mechanical wear
v The unites are stationary .The distance between printing units is
larger than that of traditional machines in order to avoid the
influence of mechanical shocks and to extend the time of link
absorption to have a good printing quality
v Enclosed double doctor blade combined with ceramic anilox roller
,can distribute the ink enenly .It can improve the effect of
printing dots of single color and multi color overprinting
v The pneumatic diaphragm pumps are used to supply the ink .There
are two inlets and two outlets in each pump which can save the ink
and have a greater efficiency .The inking system is automatic
circulated and will warm when lacking ink
v The printing roller has the function of skew emendation to the
printing plate ,which makes the hanging operation convenient
v By inputting data on the human-computer ,we can have it automatic
to adjust the gap between anilox roller and pressing roller as well
as the location of printing roller in the direction of the breadth
v The infrared drying system can be equipped as an option with each
printing unit to improve the quality and speed of multicolor
printing
The drying and conveyin
g unit
v This unit is independently driven by servo motor .It has a simple
mechanical structure which can reduce the transmission error caused
by mechanical wear
v The conveying distance is enlarged to dry the ink and avoid
scratch printing
v The breadth of infrared dying system can be adjusted according to
the size of cardboard and the power can be adjusted according to
the feeding speed to save the energy
